Ionic 1.1.0 Android 4 - Flexbox support

On Android 4.1, 4.2 and 4.3 (Jelly Bean), these two things are wrapping when they should be on a horizontal line together:

Grid:

<div class="row">
  <div class="col col-50">
    Left
  </div>
  <div class="col col-50">
    Right
  </div>
</div>

Tabs:

<ion-tabs>
  <ion-tab title="Tab 1">
    <ion-nav-view name="tab1-content"></ion-nav-view>
  </ion-tab>
  <ion-tab title="Tab 2">
    <ion-nav-view name="tab2-content"></ion-nav-view>
  </ion-tab>
</ion-tabs>

This is my current fix: https://gist.github.com/SERVANT14/f42a6f0f68545811cc68

Is there a better way? Isn’t Ionic supposed to support Android 4.0.0+? At least Jelly Bean+?!

Jelly Bean is on about 1/3 of all devices currently: http://developer.android.com/about/dashboards/index.html#Platform
